Overview

The Electro WarmFlo Select Electric Plenum Heater EM-WU254D5-SL2 is an add-on to an existing Oil, Propane or Natural Gas Furnace or Two Stage Heat Pumps. If you want to connect to 1 or 2 Stage Air Conditoner - then look at our WarmFlo Select SL1 Series Plenum Heaters.

The Electro Electric Plenum Heater EM-WU254S8-SL1 allows you to use electric heating inconjuction with your furnace or switch to just electricity if the cost of Oil, Propane or Natural Gas get's too high.

The WarmFlo Electric Plenum Heater EM-WU254D5-SL2 enhances overall heating system comfort, performance, and efficiency. Whether you are combining a gas or oil fired furnace or adding an air source heat pump, WarmFlo can maximize your heating system’s performance by monitoring outdoor and warm air plenum temperatures. Complete all-inclusive controls make installation and setup easy. Using our dual energy selector makes switching energy types as easy as a “flip of the switch”.

This WarmFlo Select Electric Plenum Heater EM-WU254D5-SL2 can be used in conjunction with a double stage heat pump. This unit is compatible with single or multi-stage gas or oil furnaces with or without variable speed blowers. This Electric Plenum Heater includes automatic dual fuel control, with manual override switch. A conventional 4-wire thermostat must be used when installing with a heat pump. This unit will not work with a heat pump thermostat.

When used with heat pump and gas/ oil furnace:Overcomes heat pump “cold air syndrome”Adjustable minimum warm air temperatureProportional control - outlet temperature ramps up with decrease in outdoor temperatureProvides a control technology for utilizing the high efficiencies of a heat pump down to atleast 0 Degrees FGenerally provides $400+ annual operating savings compared to dual fuel HP installations

When used with a gas/oil furnace:Full electric element modulation with target temperature outputSimplified system control wiringBuilt-in over-temperature protectionAir conditioning compatibleOptional outdoor sensingFull kW demand - does not come on unless required by outdoor temperature
